Display Settings & Multiple Monitors

I have a new project in prototype and there will be multiple (up to 6)
monitors (displays). Some displays will be fixed internal displays (DVI)
while others will be external flat panel or standard CRT monitors (VGA).

The issue that has risen is needing the ability to allow the user to change
display properties of any external display while preventing users from
modifying display properties of any fixed internal displays.

To avoid the questions of why would I want to do this, it has to do with the
DVI to VGA converter card being used. The card is inexpensive but only
handles one resolution (probably why it's so cheap). External displays use a
second video controller and don't need the video signal to pass through the
converter.

Thanks in advance.

Have you considered denying user access by setting Registry key
permissions for the graphics adapter Hardware Profile section for the
DVI to VGA card?

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware
Profiles\Current\System\CurrentControlSet\Services\XXXX

where XXX is IALM for Intel 845, I81x for Intel 815, NV4 for Nvidia,
etc.

HTH, Roy
